Running autoconfig erroring out with error >: XML-20190: (Fatal Error)

Hi,

Some times after manual modification of context file we might face weird errors during execution of autoconfig as below.

        at java.awt.EventDispatchThread.run(Unknown Source)

Solution:

This happens when you do manual chnages and don't update the values properly. To resolve the issue need to review the changes in the context file and make sure that the syntax is correct in the context file.
